_An Account of the Rise and Attempts, of a Way to conveigh Liquors
immediately into the Mass of Blood._

Whereas there have lately appeared in publick some _Books_, printed beyond
the Seas, treating of the Way of _Injecting liquors into Veines_; in which
Books the _Original_ of the _Invention_ seems to be adscribed to others,
besides him, to whom it really belongs; It will surely not be thought
amiss, if something be said, whereby the true _Inventor's_ right may beyond
exception be asserted & preserved; To which end, there will need no more,
than barely to represent the _Time_ when, and the _Place_ where, & among
whom it was first started and put to tryal. To joyn all these circumstances
together, 'Tis notorious, that at least six years since (a good while
before it was heard off, that any one did pretend to have so much as
thought of it) the Learned and Ingenious Dr. _Christopher Wren_ did propose
in the _University_ of _Oxford_ (where he now is the Worthy Savilian
Professor of _Astronomy_, and where very many Curious Persons are ready to
{129} attest this relation) to that Noble Benefactor to Experimental
Philosophy, Mr. _Robert Boyle_, Dr. _Wilkins_, and other deserving Persons,
That he thought, he could easily contrive a Way to conveigh any liquid
thing immediately into the Mass of Blood; _videl_: By making Ligatures on
the Veines, and then opening them on the side of the Ligature towards the
Heart, and by putting into them slender Syringes or Quills, fastened to
Bladders (in the manner of Clyster-pipes) containing the matter to be
injected; performing that Operation upon pretty big and lean doggs, that
the Vessels might be large enough and easily accessible.

This Proposition being made, M. _Boyle_ soon gave order for an _Apparatus_,
to put it to Experiment; wherein at several times, upon several Doggs,
_Opium_ & the Infusion of _Crocus Metallorum_ were injected into that part
of the hind-legs of those Animals, whence the larger Vessels, that carry
the Blood, are most easy to be taken hold of: whereof the success was, that
the _Opium_, being soon circulated into the Brain, did within a short time
stupify, though not kill the Dog; but a large Dose of the _Crocus
Metallorum_, made another Dog vomit up Life and all: All which is
